Mazda 6 Denso Lambda off

**simaservis1108** · 23rd January, 2018, 11:10 AM

Hello guys,

I did DPF off on this file 2 years ago and it was all good.
Customer comes now says DPF lamp is on and car in safe mode.
I scan the car and this 2 DTC's show:
P0030 O2 Heater Control Circuit Bank 1 Sensor 1
P0133 O2 Sensor Circuit Bank 1 Sensor 1

Can anyone do Lambda off on this file please?

Regards,
Sima

Hm... if this was my customer... I would have told him - "Go ~~~~ yourself!"
Actually this sensor is not DPF related.
And if he don't want to service such car, with many "electronic things"... tell him to drive a car with Perkins engine...

Yes,but explain that to him.
Official service told him it is DPF related.

I have the same problem. DTC P0133 and limp mode. This problem comes now, after some time of DPF off. Can be DPF off releated problem or just simple lamba sonda is bad? I think this beacuse in this car sonda placed after DPF and it is maybe sooty because DPF drilled.
Possible to switch off lambda in this ECU?
